So my wife and I were discussing this and I thought I would pose it here to get a wider set of responses.

Imagine a world where everything was pre-destined (I happen to subscribe to this. Things have happened to me that led me to believe this.)

Every day, I have choices and make them. I believe that no matter what choice I end up making, it was pre-destined to be that way. So to me, I still retain free will.

My wife disagrees and says that they are mutually exclusive. Either you have free will, or things are pre-destined.

Does anyone have any opinions on this?

There is no predestination, most things that happen that we cannot understand are disconnected and very little of what happens makes sense or reason.

Once you accept this, everything becomes very clear. No need for silly conspiracy theories, UFOs, Satan vs angles or anything else to explain what happens. As a side benefit, you can become self-determining instead of fatalistic.
